For scientists studying wild dolphin populations, being able to identify individual dolphins is a vital component of their research. In this week’s episode, learn how scientists are able to tell one dolphin from another.
Have you ever had that feeling where you are talking to someone at a party and you are sure that you have met them before but you just can’t seem to place them? Did you meet them at your cousin’s wedding last summer maybe? Did they go to elementary school with you perhaps? This can be frustrating.
Here is a news flash: dolphins do not have arms or legs! OK, OK, so that is hardly news. Surely everyone knows that dolphins have flippers instead of arms. Or, is it flippers instead of legs? Or, are they called fins? Fins, flippers… uh oh, what exactly are all those special dolphin appendages called?
This sounds like a job for “Dolphin Anatomy Terminology Man”.
In the dolphin brain, breathing is controlled consciously – that means that a dolphin has to think about every breath it wants to take before it takes it. Learn how dolphins sleep, and still manage to control their breathing.
Your breathing is controlled by parts of your brain called the medulla oblongata and the pons – they are located deep in your brain-stem down at the base of your brain. These little guys are in control of a lot of very important things that you do, including keeping your heart beating.
Today, September 20th 2006, marks an international day of protest initiated by a consortium of scientists against the annual Japanese dolphin drive hunts. The goals of the campaign are to raise public awareness of the dolphin drive hunts, and to boost measurable support through the group’s website petition which currently includes over 22,000 signatures, including many noted marine mammal scientists.
Last week, we produced a podcast titled ‘the dim dolphin controversy’. You may recall from this episode that many scientists referred to the work of Dr. Louis Herman’s research lab when citing examples of intelligent dolphin behavior. In this week’s episode, we will learn what Dr. Herman’s research has taught us about dolphin behavior and why these studies are considered by many to be proof positive that dolphins are smarter than the average goldfish. In fact, even smarter than the above-average goldfish.

This week’s episode features a discussion of the terms whale, dolphin, and porpoise.
Just how well can dolphins hear?
A special research news update – the hypothesis that dolphins can use loud bangs or deafening click sounds to debilitate, stun or even kill their prey has been kicking around the scientific world since the 1980s. Learn how new research reveals that this Killer Dolphin Sonar hypothesis is not all that it’s cracked up to be.
Can dolphins kill or stun prey with loud sounds? It certainly seems that way if you believe following headlines: Dolphins’ killer sonar confirmed from ABC Science Online February 2001. Killer clicks from New Scientist 1 January 2001.
Learn why the most famous dolphin squeak of all is actually a fraud. This episode looks at one of the most recognizable and famous dolphins sound of all time, and gives an in depth explanation as to why it may not really be a very good example of a dolphin sound at all.
You may recognize this sound – it is the ever-popular and greatly over-used dolphin squeak sound that is played whenever a dolphin makes an onscreen appearance for TV or in the movies. But, there is something fundamentally wrong with this sound.
This is the very first episode of our innovative science podcast dedicated exclusively to all things dolphin. The Dolphin Pod will bring you up-to-date and scientifically accurate information on dolphin behavior, cognition, communication, anatomy; you name it, and we’ll talk about it. We will also, on occasion, cover dolphin events in the news, summarize and explain the results from recent studies on dolphins and interview scientists currently working on dolphin-related research projects.
